@Salbayeng... "I imagine a rhinocerous would make a decent size hole in such a wall?"

Well yes, but where I lived there were not too many of them nearby. One place I lived we did get Kudu (large antelope with spiral horns) eating our roses at night, but nothing worse than that, Elephants have been known to demolish stuctures that are not too well built by rubbing their backsides against them to get a good scratch. But most animals are too clever (and shy) to try this sort of thing....

One of the things I picked up from Harbor freight a decade ago? , was a 2-stroke petrol driven drill, I used it to drill heaps of 1" holes in fenceposts , then having put up a km of fences , sold the used drill for twice what I paid for it.

Reminds me of the time I went to a great deal of trouble to carry a $20 bottle of excellent Hunter Valley chardonney all the way across the pond to friends in Buffalo, only to find the exact same wine in a bottleshop on NF Boulevarde for $10 ..

An electrician was drilling a 1/4Hole througha 1/8" steel wall to mount a cable tray or something.

All was going well until BOOM - FLASH suddenly a ragged 1" charred hole appeared, he had neglected to check on the position of the 415v 3ph feeder on the other side, fortunately the worker was not permanently injured.

Actually my favorite hole making tool is a (hand-held) plasma cutter, you can carve any shaped hole including slots, curved holes , half holes, and also cut through welds without damaging the metal on either side. Pity it only cuts metal (and strategically misplaced leather gloves and thumbnails...ouch).

I spent some time this past weekend at my local Ace and Lowe's hardware. If you're looking for a drill Made In USA, you're out of luck. If you're looking for one not made in China, there are some options.

At Ace, I found a large Milwaukee made in the Czech republic, and some other drills (DeWalt IIRC) made in Mexico.

At Lowe's, I found a large, expensive ($400) Bosch made in Germany (interestingly, a much more affordable Bosch jig saw was made in Switzerland). A lot of the DeWalts were made in Mexico, and IIRC, another Bosch was made in Malaysia.

As far as the coordless drills go, some of the DeWalts were made in Mexico.

@DavidAston Though he wasn't screwing around, the result was more like the show Jack***. No videos, unfortunately. Here's an even better story: A friend of mine was at a gym and saw a runner fly off the back of a treadmill. The friend went over to turn off the treadmill and stepped onto the belt to do so. Guess what? Now a pile of guys at the back of the treadmill!

In conjunction with unveiling of EE Times’ Silicon 60 list, journalist & Silicon 60 researcher Peter Clarke hosts a conversation on startups in the electronics industry. One of Silicon Valley's great contributions to the world has been the demonstration of how the application of entrepreneurship and venture capital to electronics and semiconductor hardware can create wealth with developments in semiconductors, displays, design automation, MEMS and across the breadth of hardware developments. But in recent years concerns have been raised that traditional venture capital has turned its back on hardware-related startups in favor of software and Internet applications and services. Panelists from incubators join Peter Clarke in debate.
